As for Mac OS X version 10.7, the one-day sales number was over one million. "Lion is off to a great start," Apple head marketeer Phil Schiller said in a Thursday press release, exulting in his perception that "user reviews and industry reaction have been fantastic."

As of mid-afternoon San Francisco time, Apple's Lion had been rated by nearly 10,000 Mac App Store shoppers; 87 per cent of them gave it five out of five stars, while 3 per cent gave it the lowest rating of but one star.

Over at MacInTouch, the Mac geekerati are busy weighing in – with quite a bit of good discussion about the demise of the PowerPC code translator, Rosetta – and the forums at MacFixIt and other fanboi watering holes are buzzing, as well.

As of today, Apple's Lion is only available from the Mac App Store for $29.99, but a thumb-drive version will appear in August, Apple says, for a pricey $69.

Having the Mac App Store available in 123 countries worldwide undoubledly helped Cupertino achieve its 50-to-1 advantage over Lion's namesake. After all, leo leo is available in only about two dozen countries. ®
